6 Claims.

My invention relates to a roll picking machine for spinning frames wherein a needle, driven at high speed, is used to remove from the drawing rolls for spinning, and particularly a long draft spinning, the lint that tends to accumulate and form slubs in the yarn.

More particularly, my invention contemplates a novel power take-off means by which the needle can be driven from the spinning frame itself by means of a flexible drive shaft and utilized effectively and economically to clean its rolls.

My invention further contemplates devising a power take-off which is portably mounted for movement to different operating positions along the frame and which comprises a pulley positioned to engage a spindle driving belt without interference with its driven spindle pulleys, and which is adapted to derive from said belt the requisite R. P. M. for a direct drive of the cleaning needle.

My invention further comprises the provision of a mounting bracket adapted to be clamped to the ring rail of a spinning frame and carrying a pivoted spring-pressed bearing frame in which the power take-off pulley is journalled, the bearing frame preferably carrying a top guide for the flexible shaft and suitable stop means to limit the engagement of its take-off pulley with the driving belt it is set to engage.

My invention further comprises the novel details of construction and arrangements of parts which, in their preferred embodiment only, are hereinafter more particularly described and claimed, reference being had to the accompanying drawing which forms a part of this specification, and in which:-

Fig. V1 is a partial transverse vertical sectional view through a long draft spinning frame showing my improved cleaner attachment in operating position with its flexible drive shaft broken away.

Fig. 2 is a detail elevation of the power takeoff apparatus complete as viewed from its side toward the frame.

Fig. 3 is a cross sectional view on the line III-III of Fig. 4 showing the power take-off in operative relation with its driving belt.

Fig. 4 is a side elevation of my cleaner drive attached to the ring rail of a spinning frame from which the spindles, pulleys and their driving belt are omitted.

Similar reference numerals refer to similar parts throughout the drawing.

In the embodiment of my invention illustrated, I show a spinning frame comprising samsons 5 carrying rails 6 and 1, upon the former of which are mounted ring bearings 8 for the spindles 9 which have pulleys l0 adapted to be driven in groups by tape or belt drives it from the power drum frame. Upon the upper rail l3 of the frame is mounted a stand l4 carrying a long draft system of rollers conventionally illustrated and generally designated by the numeral I5 and which, being of standard construction, need not be illustrated and described in detail.

The rolls of such frames require frequent cleaning and it has been found that a needle such as IE5 when rotated at high speed, say around 2560 R. P. M., will, as it is moved along the rolls and in and about the roll bearings, pick up the lint that tends to collect there and will wind it about the needle. This enables the operator quickly and effectively to reach into parts difiicult of access and readily to strip the lint therefrom. Such needles have heretofore been direct connected to high speed electric motors but a number of practical disadvantages have been encountered in such use and the object of my invention is to devise a power take-off that will enable the needle to be satisfactorily driven from the spinning frame itself. To this end I propose, as one means for portably mounting my power take-off, to utilize a clamp bracket I! having a set screw l8 adapted to engage the outer edge of the upper rail 6, the bracket having lateral extensions I9 which lengthen its bearing against the ring rail edge and steady its outer end in which I mount a vertical bearing pin 20. Upon this pin 2, as an axis, I mount a swinging pulley bearing frame comprising a lower leg 2| and an upper leg 22, with a vertical leg 23 connecting them at an intermediate point beyond which their overhung ends are bored in alignment to fit on and pivot about the pin 20, with the lower arm resting on the bracket. The other ends of these legs 2| and 22 are enlarged and bored to form bearings for the shaft 24, upon which a power take-off pulley 25 is keyed with its hub working with a close fit between the upper and lower shaft bearings. The latter bearings can have any suitable bushings or antifriction elements as may be desired.

On the upper leg 22 I mount a standard 26 with its upper end angled and provided with a guide 21 in alignment with the shaft 24 and having a central opening through which a flexible drive shaft 28 passes freely, this shaft having a coupling 29 by which it is connected to the shaft 24 and having at its other end. a coupling 30 to receive l2 running lengthwise of the spinning the needle l6 and connect it to the drive element 3| in the flexible shaft 28.

Under the leg 2| I mount a depending bracket 22 carrying an adjustable stop screw 33 disposed to engage the frame rail 6 and check the inward swing of the pulley frame responsive to the action of a spring 34 which is connected to the lower frame leg 2| and to a stud 35 on the adjacent clamp flange #9.

In operation, the clamp bracket I! is applied over the flange of the ring rail 6 and clamped with the pulley 25 in position to engage a tape or belt ll between the pair of spindle pulleys which it drives, as is shown more clearly in Fig. 3. When the swinging frame is released, its spring 34 will hold its pulley 25 pressed against the selected driving belt while its screw 33 will stop the swing of the frame and prevent the pulley 25 coming in contact with either of the adjacent spindle pulleys ill.

The belt ll runs very fast in the normal drive of the frame and the pulley 25 is designed to frictionally engage it and to be driven therefrom at the desired R. P. M., its drive being transmitted through shaft 24 and coupling 29 and drive element 3| to the needle 16. This needle is free to be manipulated by the operator and be passed over all parts of the rolls and through bearings so as to effectively clean them of lint. The power take-off can be readily shifted along the frame and the latter quickly and effectively cleaned.

My invention contemplates any portable mounting for the power take-off pulley means to hold it in proper working relation for the selected belt I l by which it is to be driven.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications, without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in the appended claims.

What I claim as new and desire to secure by Letters Patent, is:

1. A portable power take-01f for cleaning devices of spinning frames having flexible drive elements for the spindles, comprising a power takeoff pulley, means to mount said pulley for rotation about a vertical axis above the spinning frame rail and in position to contact a flexible drive ele ment for the spinning spindles, a flexible shaft driven by said pulley, and a cleaning needle driven by said shaft.

2. A power take-01f device according to claim 1, in combination with spring means to press the take-off pulley toward its flexible drive element, and an adjustable stop adapted to engage the frame and hold the power take-off pulley from contact with the spindle pulleys.

3. The combination with a spinning frame having spindle pulleys and flexible driving belts therefor which engage a plurality of adjacent spindle pulleys, of means to mount a power takeoff pulley in engagement with a drive belt between adjacent pulleys which it drives, means to hold the take-off pulley in driving relation to such belt free of contact with the belt driven spindle pulley elements, a flexible shaft driven by said power take-off, and a cleaning needle driven by said shaft.

4. A device according to claim 3, in which the mounting means for the power take-off pulley comprises a clamp adapted to be secured on the ring rail of the spinning frame and having pivoted thereto a swinging frame in which the power take-off pulley is mounted.

5. A device according to claim 3, in which the mounting means for the power take-off pulley comprises a clamp adapted to be secured on the ring rail of the spinning frame and having pivoted thereto a swinging frame in which the power takeoff pulley is mounted, and a spring interposed between said frame and the clamp in position to urge the power take-off pulley toward said driving belt.

6. A device according to claim 3, in which the mounting means for the power take-off pulley comprises a clamp adapted to be secured on the ring rail of the spinning frame and having pivoted thereto a swinging frame in which the power takeoff pulley is mounted, a spring interposed between said frame and the clamp in position to urge the power take-off pulley toward said driving belt, and an adjustable stop to limit the swing of said pulley bearing frame toward said driving belt.
